ACETYLENE-GAS BURNER.

SFECIFICATION forming part of Letters Patent N0. 77 3,552, dated November 1, 1904.

Application filed January 18, 1904. Serial No. 188,843. (No model.)

To all whom it may concern.-

Be it known that I, VVALTER H. DRAKE, 'a citizen of the United States, residing at Cleveland, Cuyahoga county, Ohio, have invented certain new and useful Improvements inAcetylene-Gas Burners, of which the following is a specification, that will enable those skilled in the art to which my invention pertains to make and use the same, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to burners particularly adapted to burning acetylene or other very rich gases. Its objects are to produce a burner that may be easily and cheaply constructed, that will be eflicient in action, and that will prevent carbonization of the gas at the minute escape-orifice of the metal base by the removal of the point of combustion to a suitable distance therefrom and the employment of a perforated non-metallic and noncombustible disk between the flame and. said base, said disk being held suspended by a very light metal frame and surrounded on all sides by the open air, so that no material amount of heat from the flame reaches the metal base either through direct radiation or through the conductivity of the metal supporting-frame.

The invention consists of a hollow metallic base having the usual small aperture for the escape of gas, a light metallic frame secured to the base and supporting at a suitable distance from it a non-metallic and non-combustible disk open to the air on both sides and provided with a central aperture through which passes the jet of gas to the point' of ignition at the farther side of thedisk.

The accompanying drawings show my invention in general form and detailed construction as I now prefer it; but changes obvious to a skilful mechanic and not requiring the exercise of invention might be made in the details and assemblage of the parts without departing from the spirit of my invention as set forth in the claims at the end of this specification.

Figure 1 is a vertical central section through an acetylene-burner embodying my invention. Fig. 2 is a perspective view of the disk-holding ring or cap. Fig. 3 is a similar viewof from any foreign substances which might effect lodgment therein.

Suspended at a suitable distance above the orifice is a disk G, composed of some nonmetallic non-combustible material, preferably of asbestos cardboard, which is also a good non-conductor of heat, while being slightly porous and entirely flexible, and therefore impervious to the effects of heat. This disk has a central orifice 0 in axial line with the orifice in the base and of slightly larger diameter than said orifice. To support this disk, 1 cmploy a slight metal frame D, made, preferably, from stamped sheet metal and composed of two rings (Z and cl, joined by side bars (Z and the upper ring being provided with inturned lugs (Z as shown. The disk C rests upon these lugs d and is secured in place byaholding annular cap or ring E, which bears upon the top of the disk at its outer edges and fits tightly with its depending flange around the ring cl of the supporting-frame. The lower ring (Z of the frame fits upon the upper end of the base, preferably bearing against a slight shoulder a as shown.

It will be observed that the jet of gas f is escaping from the orifice a of the base, is projected across the space between the point of the base and the disk,and through the orifice in the disk to the point beyond it, where combustion takes place. The disk therefore lies between the flame and the metal base and interposes to cut off any direct radiation of heat from the flame toward the base.

The parts of the disk-supporting frame are made as light as possible in order that there may be no heavy masses of metal to conduct the heat down into the metal base. There is practically no inclosed space between the base and disk, and there is therefore a free circulation of air on both sides of the disk and all around the side bars (Z of the frame, so that any heat getting into the upper ends of these bars is more likely to be radiated off into the air than to be conducted by them down into the base. By these means I am enabled to keep the base at points near the escape-orifice so cool that there is no tendency for the gas to form carbon upon it, and thus clog the passage for the gas.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. in an acetylene-gas burner, the combination of a base having a small discharge-orilice, and a perforated disk composed of nonmetallic, non-combustible, fibrous material. with means for openly supporting the disk above the base with its aperture in line with the orifice in the base.

2.'In an acetylene-gas burner, the combination of a base having a small discharge-orilice, and a perforated disk composed of asbestos cardboard, with an open frame having side bars which rest upon the base and support the disk above it in such manner as to make practically no inclosure between the base and disk, substantially as described.

3. In an acetylene-gas burner the combination of a base with its small discharge-orifice, a supporting-frame attached to the base and having open side bars, a ring supported away from the base by the side bars with a perforated disk composed of porous non-metallic, non-combustible material and resting upon the ring and an annular cap holding the disk in position on the ring, substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
